“This is incredibly ambitious”

Every three years, the World Energy Council explores possible developments of the global energy system under different scenarios. Tom Kober, head of the Energy Economics Group at PSI and one of the lead authors of the study, explains what the individual projections mean and how global warming could be mitigated. Since 2010, the World Energy Council has been developing these World Energy Scenarios and publishing them every three years…

SCCER BIOSWEET Annual Conference 2019

The 6th Biomass for Swiss Energy Future Conference was held at HSLU in Horw on September 3, 2019. Approximately 80 attendees listened to nine presentations, studied the 35 posters along the most relevant biomass value chains in Switzerland, and networked with members of the biomass energy research community and with technology application partners. This year‘s event focused on producing…

Modelling and validation of biomass combustion in a screw burner

A combined 1D-fuel-bed and 3D-CFD model for the simulation of an innovative 35 kW screw burner has been developed and validated with experiments. The 1D-fuel-bed model is a further development of a previously presented walking column approach and accounts for the special transport conditions in a screw burner. A new reduced chemical mechanism…

Scale-up methodology for automatic biomass furnaces

This work presents a methodology to perform the scale-up of a solid fuel furnace to a higher heat output with maintaining or improving the burn-out quality. As basis to derive the scale-up concept, an example of a 35 kW screw burner for biomass fuels is investigated. Based on the Pi-theorem, the relevant dimensionless parameters are derived and similarity rules for the…
